Hands down the best panel I saw at Comic-Con this year was for director Bryan Singer’s ambitious sequel X-Men: Days of Future Past.  Not only did the footage look great, but the Q&A with nearly the entire cast made for a funny, engaging, and earnest conversation.  Singer and many of the actors onstage—including Hugh Jackman, Ian McKellan, and Patrick Stewart—made the trek to Comic-Con over a decade ago with the first X-Men film, and now they were making a triumphant return the place where it all started.  Everyone onstage seemed genuinely grateful to the fans for embracing them all those years ago, and the panel fittingly ended with a standing ovation.  In celebration of the Comic-Con appearance, Fox has now unveiled a couple of swell posters for the film, which tease the time-travel element of the story as we see the different versions of Professor X (Stewart and James McAvoy) and Magneto (McKellan and Michael Fassbender).
